When evaluating CBCT (cone beam computed tomography) imagery used to help periodontists choose sites for implant placement, there are two different types of “slices” to look at — oblique slices and orthoradial slices. The orthoradial slice is straight up and down, while the oblique slice is slanted, similar to a forward slash on a computer. These slices help periodontists visualize the anatomical structures in the mouth and evaluate where the optimal placement of a dental implant would be. Although which slice is used depends largely on the treating periodontist’s preferences, studies are showing that the oblique slice tends to be more accurate than the orthoradial slice, helping periodontists to achieve better patient outcomes. Oblique slices tend to be a better choice than orthoradial slices for implant placement in the posterior region or when planning implants that are tilted and if orthoradial slices are used, caution should be exercised.
